I am a postdoctoral researcher setting up an auditory neuroscience lab.
We already have a quite decent speaker and amp (ES1 and ED1 from TDT), so we only need an audio interface. So I thought a 192kHz DAC would work.
So I am thinking about using Raspberry Pi 4 with HiFiBerry DAC2 HD.
My question is,
Is the DAC able to play up to 90kHz without significant frequency response rolloff?
I found this thread https://support.hifiberry.com/hc/en-us/community/posts/201846541-Ultrasonic-Frequency-Response-
and apparently it's okay but the question is 5 years old and for another product.
I don't think I can use any cheap 192kHz DAC b/c I found out that many DACs have low-pass filter at 20kHz and doesn't have good compatibility with the Pi. Of course one solution could be the RME fireface which does have great frequency response but it costs $1300 and I only need one channel :)
So I hope HiFiBerry works!
